Code​:
say "7\x[308]".NFC ~~ /^ \d+ $/

Result (2015.12,2016.10)​:
｢7̈｣

Result (2016.11,HEAD)​:
｢55｣

Previously it worked with NFC objects as if they were strings, which intuitively makes sense. However, I'm not going to claim that this is what it should do, I'm just pointing out that the behavior was changed.

Right now it works with the .ord of the first character, this is probably less than awesome.

The change is a result of both rakudo/rakudo@05b65d0 and rakudo/rakudo@33eeb32

From @usev6

Unfortunately commit 8d35951 breaks the build on JVM. It dies during stage parse with

Error while compiling, type X​::Parameter​::InvalidType
  suggestions​: ()
  typename​: Uni
at line 32953, near " $uni) { "
  in panic (gen/jvm/stage2/NQPHLL.nqp​:348)
  [...]

Type Uni is not usable with rakudo-j​:

$ perl6-j -e 'my Uni $foo'
===SORRY!===
Type 'Uni' is not declared
at -e​:1
------> my Uni⏏ $foo
Malformed my
at -e​:1
------> my⏏ Uni $foo

I'd suggest to add a special case for jvm, so that fix from commit 8d35951 is not applied there. I opened a PR for that​: rakudo/rakudo#980

From @moritz

Tested in https://rt-archive.perl.org/perl6//Public/Bug/Display.html?id=130458

Note that this is still not perfect, for example $/.orig doesn't contain an NFD after the match, but that's not in the scope of this ticket.

@moritz - Status changed from 'open' to 'resolved'
